| |
From: Tom Rix <trix@redhat.com>
commit 5950bdc88dd1d158f2845fdff8fb1de86476806c upstream.
Clang static analysis reports this issues ice_common.c:5008:21: warning: The left expression of the compound assignment is an uninitialized value. The computed value will also be garbage ldo->phy_type_low |= ((u64)buf << (i * 16)); ~~~~~~~~~~~~~~~~~ ^
When called from ice_cfg_phy_fec() ldo is the uninitialized local variable tlv. So initialize.
